A comfortable atmosphere in a city apartment or a country house is not only an attractive design and high-quality furniture, but also warm. For complete heating of residential premises, especially country houses, use a warm floor. Unfortunately, it is not always possible to install electric heating, so people prefer water systems. If there is no centralized heating system, an electric boiler for a warm water floor is also installed.
Features of floor heating without radiators
There are several varieties of floor heating systems - infrared, electric and water. In most cases, landlords give preference to water systems. The heat carrier continuously circulates through the main pipes, which is heated in a special electric boiler for a warm floor.
Boilers are often used to heat rooms for various purposes, for example, residential apartments and houses, offices, garages, etc. This demand and prevalence is due to the complete safety of use in rooms with people and compact size. Modern heating systems are additionally equipped with temperature control sensors, which will allow you to adjust the microclimate in the rooms.
Despite the large number of advantageous features, builders do not recommend being limited to installing a warm floor only. Necessarily need heating radiators. To maintain the optimum temperature in the house, the floors will have to be heated up to at least +30 degrees. Many floor coverings do not withstand such conditions. Thanks to radiators, the air in the room warms up faster and more evenly.
Types of boilers for underfloor heating
Boilers for heating the coolant are divided into several varieties. They differ in operating features, installation method and fuel, due to which it works.
Diesel boilers
These modifications work thanks to diesel fuel. Such models are characterized by high performance and efficiency, they are completely autonomous in their work.
Boilers are quite easy to install, they are easy to use, have high efficiency (COP), consume small amounts of fuel.
Solid fuel equipment
Fuel for such modifications are pellets and firewood. The principle of operation has much in common with burning wood in a conventional stove. Combustion occurs at high temperatures (more than +250 degrees), there is no air access. The coolant is heated due to the emission of hot smoke during fuel combustion.
Solid propellant varieties of boilers in residential buildings are rarely used, they are most common in industries and in agriculture. Operation at home is complicated by the need to constantly load firewood or pellets.
Gas boilers
The equipment runs on gas. The boiler body is mainly made of steel or cast iron, which guarantees a long service life.
Steel models are much lighter in comparison with cast iron, they have compact dimensions, they are maintainable. Cast iron models have a longer service life, but the cost is slightly higher. The systems can operate on main gas and liquefied gas cylinders. The devices are economical; low-power models can be used for underfloor heating.
Electric boilers
Electric boilers can be used in all spheres of human activity. The advantage of such devices is that they allow you to realize low-temperature floor heating.
Calculation of boiler power
Calculation of boiler power is performed according to a special formula. It is believed that for every 10 sq.m. must account for at least 1 kW of thermal energy. If homeowners plan to install a dual-circuit boiler, an additional 30% must be added to the result.
In parallel, it is important to take into account the features of the double-circuit boilers. When connecting a hot water supply, the heating medium does not stop. At these moments, the wiring is subjected to peak load, therefore, the wiring must comply with all technical parameters prescribed in regulatory enactments.
The results are always rounded up.
Criterias of choice
An electric boiler for a warm one can be difficult to choose because of the wide range of equipment in stores. The following points are determined:
- Manufacturer. Italian, Czech, German and Russian manufacturers specialize in the manufacture of electric boilers.
- Power, which is calculated by the heated power.
- The functionality of the equipment. Not all household electric boilers are designed to connect a warm floor to them.
If you can’t choose the equipment yourself, it’s best to consult a specialist.
Top manufacturers
There are a large number of manufacturers of electric boilers, but judging by the technical characteristics and experience of use, it is better to give preference to the following brands:
- Buderus Logamax E Series;
- ATON Electro;
- Kospel EKCO;
- GALAN, a series of hearth, geyser and volcano;
- Ferroli LEB and Ferroli ZEWS;
- The master's machine factory Zh7-KEP.
It is recommended to purchase equipment from official representatives or in large chain stores that provide a guarantee and quality certificates.

Connecting an electric boiler for underfloor heating
Installation of an electric boiler, unlike diesel and gas, does not require coordination with government organizations. It can be installed independently. Installation should be carried out taking into account all the requirements of the PUE.
It is required to connect the equipment with its own cable and to its own machine, it is important to take care of grounding.
To connect an electric boiler to the water floor, an RCD is not required. It is important to equip the system with a collector assembly, which will ensure uniform distribution of hot coolant throughout the system.
